R help - Dec 2011 - Overlaying density plot on forest plot

Dear R User,

Please, I am new to R. I want to overlay density plot for predictive interval
pooled result in meta-analysis.

Frank,

Have you tried the R function overlay(), it is exactly applying to your
question.

It is hard to be sure from your rather brief question but does the 
addcred parameter to forest.rma in package metafor do what you want?

It would be helpful to cc to r-help in case someone else there knows better.

If you follow my suggestion you get a similar plot to sub-plot A in 
your example but the credible interval is shown as a dashed line 
superimposed on the summary diamond and not as a normal density as 
shown in sub-plot A. Whether that is what you want is up to you I think.
